The color has faded. It is common with that ink.

Fading is a likely culprit - red pigments (especially older ones) are notoriously unstable. Ultraviolet light can wreak havoc on most reds, and cosmic rays can add to the damage. What you have is probably the blue component of a red/blue pigment mix used to give the red violet color. The red got knocked out, leaving the much more stable blue behind.

Hello,
Thank you both for your replies. I never knew that stamps could fade into a diff. color. Red violet to blue. Well you learn something new all the time with this hobby. Paul.

Yup.
Perhaps I should re-do my experiment with a red-blue stamp!
(I need to amend that page to mention a noticeable difference in the sunlight exposed 3c stamp)

Hello from the left coast. I have been trying to I.D. this stamp for awhile. It is perf. 12 1/2 on embossed paper. It is of the King Luis type issue of 1886. SCOTT Type A2. SCOTT lists the 25 REIS as red violet. This 25 REIS is blue like the color of SC #21, the 50 REIS. Anyone out there know about this? I hope you local fireworks show is not fogged out like ours will be. Paul Wilson. (OLDPAUL).
